Z10 all whom it may concern Be it known that I, FRANK P. Koiucnr, a citizen of the United States, and residing at I Haven and State of Connecticut, have invented con i'nin new and usefu Improvements in Electrio-Gaole-Snpperting Brackets, of which the following is a specification, such as will enable those skilled in the art to which it apperiains to inake and use the same T his invention relates to electric cable supportin brackets, and particularly to devices of t iis class designed for use in manholes and similar places, and the object thereof is to provide an improved device of this class which is strong and do able and presents a neatand finished appearance, the

invention described andclainicd herein relaiing particularly to the channel bar or bars used for supporting the arms of a device of this class and to the method of connecting the separate parts, of which said channel bar or bars are composed.

The invention is fully disclosed in the fol lowing specification of which the accoin panyin'g drawing forms a part, in which the separate parts of my invent ion are designatcd by suitable reference characters in each of the views, and in which Figure l a perspective view of one of the inner walls of n manhole and showing one of my in'iproved electric cable supporting brnckets;-l{ 2 a vertical sectional view on the line 2 2 of Fig. lg-Fig. 3 llside view showing a detail of the construction of the bracket device, and;-Fig. =1 :1 cross sec tion on the line l-1- of Fig. 2, 2, 3 and 4 being enlarged.

In the drawing forming part of this specification, I haveshown at a one of the walls of a manhole and at I) my improved cable supporting bracket which comprises a vertical channel bar member 0 and detachable arms (Z connected therewith and only one of which is shown.

The channel bar member 0 comprises it back portion v'--and side flanges 0 and in practice it is frequently necessary to splice or connect a number of separate parts to dorm a channel bar member of theidesired length or height, and this invention relates particularly to this feature of the construc- Speeiilcstion of Letters Eaten-h Application filed April 11, 1913.

tion, and the channel bar member shown, is composed of two separate parts 0 and In connecting two or more parts of channel bars to form the channel bar member 0, the side flanges c at one end of one part are cut awn as shown at c" in Fi 3 to form a last named part of the channel bar member and through the tongue Q and into the Wall (1. This method of connecting the parts 0* and 0 makes n continuous channel bar inenr ber,..the back and side walls of which are flush and continuous and the said channel bar member is as strong at the points where the separate parts are connected as at any other points.

K The back of the channel bar member 0 is provided with the usual transverse openings .f ha ving downward extensions 7, and the arms d, but one of which is shown, are provided with transverse heads Z inwardly of which is a neck "portion (Z and in practice, the heads (i of the arms (5 are passe-cl bacle weirdly through the openings f and said arms are dropped down so that the necks (1 enter the downward. extensions f of said openings, as will be readily understood and this securely looks the arms to the channel bar member, but said arms may be detached Whenever dc l. My invention "however, is not limited any way to the arms (Z, nor the particular means employed for connecting them *ith the channel bar member 0.

Having fully described my invention what I claim its no and desire to secure by Letters Patent is 1. In an electric cable supporting bracket,

:1 channel bar member adapted to be secured to a wall or other support and composed of separate parts nbntted end to end, the side flanges of one of. said parts being cut away and the back thereof being formed into an inwardly set tongue which is inserted. into the abutting end of the other part.

2. In an electric cable supporting bracket, a channel bar member adapted to be secured to Wall or other support and composed of isepai'ate parts abutted end to end, sim side liking es of one of said parts being 011% may fiigliid the back thereof being fbrmed iiifi-q rm im-waidiy set tongue which isineerted mic the'abuttin' end of the other glam, and a,

belt 01* spi (6 passed through i; a back of said other part and through said tongue, into the wall or support.

In tstimony flmt I laim the foregoing as m invention I 112m; si ed m name in 10 presence of the subscribmg witnesses this 4th day of April 1913.
